hi Frank,

Below is my program,

If RenderFormat to ".Net" it Not able to work at click events on each data point but it able to changes on Datagrid.

If RenderFormat = "Image" it able to work at click events on each data point but it Not allow me to changes on Datagrid.

Actually i would like to perform these both which is click events on each data point and allow to changes on Datagrid. Is there possible??

Test1.aspx

<chartfx7:Chart ID="Chart1" runat="server" Height="450px" Width="900px" Visible="true" RenderFormat=".NET" >
  <AxisY Title-Text="Utilization %">
  <LabelsFormat CustomFormat="0" Decimals="2" Format="Percentage" />
  </AxisY>
  <AxisX LabelAngle="90" Title-Text="">
  </AxisX>
  <Series>
  <chartfx7:SeriesAttributes />
  <chartfx7:SeriesAttributes />
  <chartfx7:SeriesAttributes />
  </Series>
  <LegendBox ContentLayout="Spread" Dock="Bottom">
  </LegendBox>
  <MainPane AxisY-Title-Text="Utilization %" />
  <DataGrid Visible="True" />
  <Titles>
  <chartfx7:TitleDockable Font="Arial, 12pt, style=Bold' Text='Testing' />
  <chartfx7:TitleDockable Text="" />
  </Titles>
  <ToolBar Visible="True" />
  </chartfx7:Chart>

A click on the client will not always cause a Click event to be fired in the server, only clicks made on points are sent back to the server as a PostBack/CallBack. A MouseClick event will fire on the client everytime.

You can capture client-side event using JavaScript. For example:

<SCRIPT  LANGUAGE="JavaScript" FOR="Chart1" EVENT="MouseDown(sender,eventargs)"><!-- Chart1.AllSeries.PointLabels = true;--></SCRIPT>
